Evaluation of the feasibility of satellite systems design in the 10-100GHZ frequency range

摘要

We have presented a picture of the total attenuation to be considered in satellit ecommunication and broadcsting systems int eh 10-100 GHz frequency range. Although the findings and methodology are of general interest, the numerical results apply to the Italian (mid-latitude) sites of Fucino and Gera Lario and to slant paths of elevation angles 33 deg. C and 32 deg. Respectively. The rain attenuation probability Distribution P(A), of exceeding the value A (dB) at a given carrier frequency in an average year, has Been estimated by the synthetic storm technique and an associated formula, presently derived, which Links A to frequency for fixed probabilities.
